UNITED STATE-s 1,971,232 SELVAGE TRIMMING DEVICE Frank Pate, Shawmut, Ala., assigner to DraperA Corporation, Hopedale, Mass., a corporation of Maine Application January'22, 1934, Serial No. 707,699

9 Claims. (Cl. 139-302.)

The present invention relates to thread cutters for looms, and has more particular reference to the type of such devices usually mounted on the loom temple for trimming loose weft ends adg jacent the cloth selvage.

The conventional thread cutting devices of the type `mentioned usually leave short weft ends projecting from the selvage, which ends must be subsequently trimmed or burned on. This trimming or burning operation requires extra handling of the cloth and Vadds to the expense of production.

Accordingly, it is the object of my invention to provide a temple thread cutting device which will,on the types of cloth to which it is adapted, trim the weft ends immediately adjacent the cloth selvage, thereby eliminating the trimming orvburning operation above mentioned. My invention provides a selvage following member, which may be in the form of a block, guided inthe temple head for movements in a direction approximately normal tothe cloth selvage. Weft parting means, such as a xed cutting blade, is carried by the member for cutting the projecting weft ends. The follower member, or block, is yieldingly maintained in contact with the cloth selvage and the weft parting means is accordingly maintained close to the cloth selvage.

Two embodiments of my invention Iare illus- '30 trated on the accompanying drawings, of which: Fig. 1 is a plan view of a temple and thread cutter adapted for use on cloth that need not be stretched laterally as it is being woven;

Fig. 2 is a view showing the thread cutter parts in elevation but with the temple cut away,

or sectioned, as at 2--2, Fig. l;

Fig. 3 is a view similar to Fig. 1 but showing the second embodiment of the invention;

Fig. 4 is a sectional view, taken approximately on line 4 4, Fig. 3; and

Fig. 5 is a sectional view taken approximately on line 5-5, Fig. 1.

The temple to which my invention has been applied is illustrated in Fig. 1 as occupying the usual position relative to the cloth.- That is, the stand 1 is usually fixed to the breast beam of the loom (not shown) so that the bar 2 projects rearwardly and downwardly adjacent the selvage 3 of the cloth 4 being woven, as shown. The '56 bar 2 carries at its rearward end a temple head 5 comprised, in the present instance, of a cap 6 and pod 7. The cap and pod project laterally to receive between them the cloth selvage. The temple is reciprocated from the usual depending v5'5" heel 8.

The temple illustrated in Figs. 1, 2 and 5, which will now be described, serves to support the cloth selvagebut does not embody -meansior stretching the cloth later-ally. The cap 6 isrcurved downwardly at its forward and rearward edges, and the podl 7 is provided with grooves 9 and 10 separated by Aa ribl1. lThe curved cap and the grooves and ridge in they pod form a guideway extending approximately normal to the selvage within which guideway a selvage following member in the form of a block 12 is slidably received.

The block l2 is preferably provided with a selvage-receiving recess 13which is aligned with thespace provided between the edges of the cap and pod for the passage of the cloth. A pair of i coiled springs 14, 14 are positioned within the aiorementionedguideway in the temple head and bear against the block 12 for maintaining the latter in contact with the cloth selvage.

The weft parting means is carried by the sliding block .12, In its preferred form such means is comprised solely ofa cutting blade 15 fixed to the block 12 as by being embedded therein. The` blade projects rearwardly between the cap and pod with its vertical sharpened edge 16 substantially flush with the rearward edges of the cap and pod. Since the block 12 isyieldingly held against the cloth selvage it will slide laterally thereof and, accordingly, the cutting blade will be maintained a uniform distance from the selvage. As shown in Fig. 1, the blade may be much closer to the selvage than it is ordinarily possible.

It will be noted that if the temple is set slightly forward of the fell 17 of the cloth, as shown in Fig. l, this xed blade type of weft parter is not operative until several picks after transfer. Consequently, the weft ends, as 18, must be held taut by suitable usual means not herein disclosed.

The temple stand, bar, cap and pod shown in Figs. 3 and 4 are identical with those shown in Figs. 1, 2 and 5, and are accordingly identified by the same reference numerals. However, in this second embodiment of my invention a conventional temple roll 19 occupies the groove 10, being journalled on a pin 20 carried by the temple head. y

The selvage-contacting block 21 is cylindrical in cross-section and is actuated by but one spring 22 but is provided with a selvage-receiving recess 23 and a xed knife 24 asin the rst described embodiment. While the operation of the cutting device in this embodiment is identical with that already described, the addition of the temple roll enables the temple to stretch the cloth y laterally where such function is desired.

Having fully disclosed the preferred embodiments of my invention, I claim:

1. In a loom temple, the combination of a temple cap and pod having a guideway therein, a selvage contacting member slidably positioned Within said guidevvay, weft parting means carried by said member, and means yieldingly maintaining said member in contact with the cloth selvage.

2. In a loom temple, the combination of a temple cap and pod having a guideway therein,

a member slidably positioned Within said guide- Way, said member having a cloth selvage-receiving recess formed therein, a `thread cutting blade' carried by said member, and spring yieldingly urging said member in a direction toward the cloth selvage.

3. In a loom temple, the combination of a tempie head having a passage therethrough for the cloth seivage, said temple head having a guidevvay therein extending approximately normal to the cloth selvage,la block slidable Within said guideway, weft parting means carried by said block, and a spring yieldingly urgingsaid block into Contact with the cloth selvage.

4. In a loom temple, the combination of a temple head having a passage therethrough for the cloth selvage, said temple having a guideway therein extending approximately normal to the cloth selvage, weft parting means mounted in said guideway and coniined thereby to sliding movement in a direction normal to the cloth selvage, and means yieldingly maintaining said parting means a predetermined distance from the cloth selvage.

5,. In a loom temple, the combination of a temple head having a passage therethrough for the cloth selvage, said temple having a guideway therein extending approximately normal to the cloth selvage, a block slidably mounted Within said` guideway, a thread cutting blade carried by said block, and means yieldingiy urging said block along said guideway into contact with the cloth selvage.

6. In a loom temple, the combination of a temple cap and pod having a temple roll positioned therein With a member slidably mounted in a ,80 guideway formed in said cap and pod axially of said roll, weftparting means carried by said l member, and a spring yieldingly urging said member along said guideway into contact with the cloth selvage.

` 7. In a loom temple, the combination of a temple cap and pod having a temple roll positioned therein with a member slidably mounted in a guideway formed in said cap and pod axially of said roll, said guidevvay confining said member to movements axially of said roll, weft parting means comprised solely of a cutting blade xed to said member, and means including a spring-,

`for yieldingly maintaining said blade a predetermined uniform distance from the cloth selvage.

8. In a -loom temple, the combination of a temple head having a passage therethrough for the cloth selvage, said temple head having a guideway therein extending approximately normal to the cloth selvage, a block slidable within said guideway, weft parting means comprised solely of a cutting blade xed to said block, and a spring acting on said block to urge the latter into contact with the cloth selvage.

9. In a loom temple, the combination of temple head having a passage therethrough for. the cloth selvage, said temple head having a guideway therein extending approximately nor-Y mal to the cloth selvage, a block slidable within said guideway, said block having a cloth selvagereceiving recess formed therein, weft parting means comprised solely of a cutting blade iixed to said block, and a spring positioned Within said guideway and acting on said block to urge the l latter into contact with the cloth selvage.
